The end sections of the detonation channels extend along the layers of the matrix of the initiation unit, and the amount thereof is the same on each layer. The layers of the matrix are arranged perpendicular to the main charge. The side surface of the main charge is made expanding in the direction of detonation propagation.EFFECT: increase in the efficiency of operation due to the maximum decrease in the load diversity - the asymmetry of the surface of the detonation front formed in the main charge and due to elimination of the "cutting" impact on the loaded object of detonation of the main charge along the projection line of the side surface thereof.2 cl, 2 dwg
